Question: 1 / 400

A single cylinder Briggs and Stratton engine has:

1 valve

A single cylinder Briggs and Stratton engine only has one valve, as indicated by the answer A. Each cylinder in an engine requires at least one valve to regulate the flow of fuel and air into the cylinder and to allow exhaust gases to exit. Since a single cylinder engine only has one cylinder, it only needs one valve. The other options are incorrect because they either have too many or too few valves for a single cylinder engine. Option B would be incorrect because it refers to a two-cylinder engine, while option C and D would have too many valves for a single cylinder engine.
